Gehr Plastics Announces Huge 24″ Diameter Acetal Rod
Gehr Plastics is an industry leader in large high performance plastic materials. They announced at this years IAPD Conference in San Diego, the new production of 24″ diameter (600mm) Natural Copolymer Acetal Rod.
Being an industry leader is more than making the largest material, it is also about making the best quality material. Gehr Plastics is ISO 9001 and ISO 14001 approved and certified, guaranteeing a consistently high quality product. The product line that Gehr Plastics produces is also quite large. The materials include: ABS, Acetal (POM-C and POM-H), HDPE, Kynar, Noryl, Nylon, PEEK, PEI, Polypropylene, Polysulfone, PPO, PVC (Type 1, Type 2 and CPVC), PVDF and Ultem materials. All of these materials are available in a wide range of sizes, and yes, some of the largest.
Gehr Plastics Long History
Gehr Plastics has been leading the industry in innovation since 1932, and is now in the third generation of family owned and operation. From the wide range of materials to the extremes in size range, this is cutting edge performance from a family run company. They also released a web-app for picking plastic materials, Gehr Plastic Selection Tool, and it is also available for mobile devices. This comparison tool compares not only plastics, but metals as well, for a great look at the best physical properties for an application.
While quality and size are keystones to excellence, Gehr Plastics is also interested in materials that the rest of the industry has not

considered. Over the last several years, Gehr has produced some PLA materials (made from plants) and even a Clear Nylon Rod for higher temperature sight-glass applications. These are just a few of the cutting edge areas that Gehr Plastics is leading in this industry.
Industrial Plastics is Master Distributor
Gehr Plastics materials are sold through a tight network of Master Distributors throughout the United States. Industrial Plastic Supply, Inc. of Anaheim, CA is proud to be one of the top selected suppliers of these innovative materials.

Is HDPE Sheet and Acetal Homopolymer Sheet the same?
Here is another popular question asked by our clients. Is HDPE the same as Acetal Copolymer / Delrin Acetal Homopolymer? No, they are two totally different materials. Although the natural color of both is a milky white to opaque white, and they do look a bit similar, they are not. (HDPE is milky white to almost translucent depending on thickness, and the Acetal materials are a more opaque white to slightly milky – once again depending on thickness . See picture below of .500″ thick samples of HDPE and Acetal sheets)
HDPE and Acetal – Some Differences
The HDPE sheet and rod is a softer material, and is commonly known for its FDA certification and used in numerous food applications, such as: one gallon milk jugs, cutting boards, colored water glasses/cups, and many, many more. While it can be machined, because it is a bit softer and lighter, the tolerances it can be machined to are not very tight. It is not bondable, so it makes a great non-stick surface for sticky foods and adhesives.
The Acetal Copolymer and the premium Delrin® Acetal Homopolymer also have FDA certification, and are used heavily in the food processing industry. This material is a more mechanical material and is used in bearing and wear applications, cams, feeder screws, etc. This material is can be machined to tight tolerances, and will wear for long periods without lubrication. Due to its exceptional wear properties, it is not bondable, thus requiring mechanical fastening or threads to assemble. It has a very low water absorption, and you will find it in your toilet tank as the white moving parts in the filler mechanism. It is an extremely popular material for machinists, as it works much like soft brass.
While HDPE Sheet and Acetal Sheet look similar, they perform quite a bit differently.
While both materials are FDA approved, are machinable and can be used to make rigid wear resistant parts, they are two different resins and have drastically different physical properties. Another major difference is in the weight of these items, HDPE sheet and rod material weighs about 35% less than the Acetal sheet and rod material. Please check the data sheets for more information to assist in proper material selection.Acetal Data Sheet and HDPE Sheet Data
Acetal is commonly known as: Delrin Homopolymer Acetal, Tecaform AH,Ensital, Unital, Pomalux, Ultraform and many more.
HDPE is also known as: Ultraethylux,Densetec, Polystone G, Fortiflex, Versadur, Hostalen, and many more.
Can we get colored Acetal Copolymer – Delrin® Homopolymer Rod?
We get this question frequently.
The easy answer is yes, however, the most common available colors are Black and Natural (white in color). But to continue the thought, we have several manufacturers that run ‘Medical’ grades of Acetal Copolymer as well as Acetal Homopolymer (ie: Dupont Delrin® 150SA Homopolymer Acetal) in several colors. These materials are special run, but can frequently purchase by the standard length without a custom run. The biggest factor may be the price. The colored version of Acetal Copolymer – Delrin Homopolymer Acetal materials are dramatically more expensive.
Colored Acetal Copolymer – Dupont Delrin® Homopolymer 150SA Rod
While price is a factor, the benefits may out weigh the cost. Many of our clients use these colored rods to help differentiate their product from their competition. With colors that can come close to a logo color or match a machine, these advantages are clearly visible. Having a special color available to machine small to medium runs of your product can save you thousands over molding a new part for trials.
What colors can I get in Acetal Copolymer or Dupont Delrin® 150SA Homopolymer Acetal Rod?The range is a bit limited, but does include: brown, dark blue, dark green, gray, light blue, light green, red, rust and yellow (and of course Natural and Black).
